I got all four of my wisdom teeth taken out on the 15th of January and now I have a disgusting flavor coming from the bottom of the left side of my mouth. This taste is a mix of blood and rotten eggs and I am fed up with it. At first it came from both my left and right sides, but then I got dry socket on my right side and they packed it. after this the flavor only came from the left. I got the packing out today and the right side (where the packing was) no longer gives off this taste, but the left side still has this nearly constant taste. Why does it taste like this? How long should I expect this taste?
